Description

[Detailed description of the invention] This invention relates to a filter mounting device for air conditioners, etc., and its object is to provide a filter mounting device which makes it easy to attach and remove a filter and also increases the mounting strength of the filter by forming a guide from a rib having a specified curved portion which also serves to reinforce the casing, and by forming the filter to be elastic in itself so that the filter can be attached by deforming at the curved portion.

An embodiment of this invention will be described below with reference to FIGS. 1 to 3. In the figures, 1 is a casing;
Reference numeral 2 denotes a suction port provided at the front of the upper surface of the casing, and reference numeral 3 designates a guide serving as a plurality of reinforcing ribs arranged in parallel with the casing 1 on the inner side of the suction port, and this guide is not shown in the figure. The rear end surface 4 is formed in a continuous manner from the front wall of the casing 1 to the upper wall having the suction port 2 as shown in FIG. forms a bent portion having a predetermined curvature. Reference numeral 5 indicates an air outlet provided at the lower front of the casing 1;
7 is a grill rotatably provided at this outlet so as to change the blowing direction; 7 is a blower that forms an airflow that takes in air from the inlet 2 and blows out from the outlet 5;
The vane casing 9 is integrally formed with the casing 1, and an electric motor (not shown). 10 is a ventilation passage formed in the casing from the suction port 2 to the outlet 5; 11 is a finch-tube type heat exchanger installed in this ventilation passage for cooling by passing a refrigerant such as fluorocarbon gas through the fins 12; It is formed by arranging the pipe 3 and a heating pipe 14 for passing a heating medium such as hot water in parallel. Reference numeral 15 denotes a filter that is removably installed on the downstream side of this heat exchanger, and is formed in advance to have elasticity, and has a convex portion 16 and a handle portion 1 at the bottom.
7 are provided respectively. Reference numeral 18 is an opening provided in the casing so that the filter can be inserted therein, and 19 is a drain plate for receiving condensate condensed on the heat exchanger 11.

In the case configured as described above, the fins 12 are cooled or heated by passing a refrigerant through the cooling pipe 13 and a heating medium through the heating pipe 14, and by operating the blower 7. The air sucked in from the suction port 2 passes through the filter 15 and reaches the heat exchanger 11, where it is cooled or heated and blown out from the blow-off port 5 to cool and heat the room. Here, when the filter 15 is inserted through the opening 18 and inserted to a predetermined length, the tip of the filter 15 hits the rear end surface 4 of the guide 3, that is, the lower end of the curved part.
By further pressing the filter 15, the filter 15 is inserted while being deformed (curved) along the rear end surface 4 of the guide 3, and the protrusion 16 engages with one side of the opening 18 at the most inserted point. It is mounted so as to block the ventilation path 10. This filter can be removed by gripping the handle part 17 and pulling it downward so that the convex part 16 comes off. When the filter 15 is installed, the middle part of the filter 15 is bent in a direction away from the heat exchanger 11, so that condensate condensed on the heat exchanger 11 adheres to the filter 15 and falls along the filter. Never.

As explained above, this invention is such that the filter insertion guide is formed integrally with the casing by a rib that also serves as reinforcement for the casing, which has a predetermined bend, and the filter is deformed at the bend before being attached. Therefore, the strength of the casing is increased by the ribs, and since the ribs also serve as guides for the filter, the filter guide structure is simplified, and the filter can be easily attached and detached. Furthermore, since the filter is bent against elasticity, the mounting strength of the filter can be increased, and the structure can sufficiently withstand drafts passing through the ventilation path.

[Brief explanation of the drawing]

FIG. 1 is a cross-sectional view showing an embodiment of this invention, FIG. 2 is a cross-sectional view showing the insertion portion of a filter 15 of this invention, and FIG. 3 is a perspective view of the main parts of the casing seen from the back side. In each figure, the same reference numerals indicate the same parts; 1 is the casing, 3 is the guide, 4 is the rear end surface (bent part) of the guide, 10 is the ventilation path, and 15 is the filter.
